hold the wagon onthe platform during thisl operation; and the invention has for its object to provide an improved and simple arrangement of the raising andlowering mechanism of such apparatus. Y

Apparatus made according to theA inven tion comprises essentially a platform pivoted at one endadjacent to a hopper into which the contents of the wagon are to be discharged, a vertically movable hoisting beam pivoted at its upper end to the opposite end ofthe platform, a head on the beam capable of engaging with the rear axle of the wagon; a guiding rod (or rods) hinged at one end to the lower end of the beam, its other end being pivoted on a fixed center, a winding drum and a hoisting rope or chain passing therefrom over pulleys, the guiding rods causing the lower end of the beam to follow a prescribed path during the tipping operation. If desired, means may also be provided to counterbalance the weight of the platform and wagon.

The improved apparatus is shown on two accompanying sheets of explanatory drawings in which Figure. l, Sheet l isa plan, and Fig. 2 a vertical section, showing the improved apparatus in duplicate, one on either side of a hopper, so that if the end door of the wagon comes in the wrong direction for one tipper, it will be right for the other. Figs. 3 and 4, Sheet 2 are sectional elevations at right angles to each` other, and to a considerably larger scale of the operating beam, while Fig. 5is a horizontal section on the line A-B Fig. 4.

As shown on the drawings, there is provided a platform C consisting of side beams and connecting framing. This platform is hinged at its inner end to girders C1 extending over a hopper C2 into which the contents of the wagon C3 are to bo tipped.

The platform extends between railsB (Fig.

t)v over which the wagon to be tipped is run.y Pivoted to the free end of the platform C, there is what may be termed a hoisting beam D1,.composed of side members braced together. iThe head o f this beam hasin it a groove D2 capable of engaging the rear axle of the wagon, as hereinafter described. To thelower end of this beam,y D1 there is pivoted one end of a pair of guiding .rods G, the opposite ends of which are pivoted Vto the under side of the hopper C2. A windingV drum G1 kdriven through gearing G3 from .ag prime mover G1, has secured toits opposite ,ends the two ends of a hoisting rope El.k The rope passes down to and under pulleys Hzron alspindle J turning in bearings provided for itin the lower end of the beam D1, then up toy and over pulleys J2, the spindle zfor which is carried in stationary bearings. From the pulleys last mentioned,the loop ofthe rope passes to and around a pulley K, the bearings for the spindle of which are carried in blocks K1, connected to a weight K2 capable of sliding between fixed girders K3.

'From extensions on the ends of the winding drum G1 ropes pass over pulleys L to weights L1 which counterbalance the weight of the empty wagon and of the platform.

To tip a wagon C3 which has been run over either platform C, the winding drum G1 is started in the appropriate direction to cause the hoisting rope H to apply lifting strain to the pulleys H2 on the lower end of the hoisting beam D1 and consequently start to raise that beam. The groove D2 in the head of the beam D1 then immediately engages with the rear axle of the wagon, and during the continued upward movement of the beam, its lower end follows the path prescribed by the travel of the guiding rods G and the upper endl of the beam D1 travels in the arc prescribed by the travel of the platform C. The continued upward travel of the beam D1 raises the platform C on its pivot and carries the wagon C3 into the tipping position, the front axle of the wagon resting on the platform during this move ment, and the wagon being held on the platform by the groove D2 in the head on the beam D1 engaging theA rear axle of the wagon. The upward movement of the parts is facilitated by the Weights L1 counterbalncing the weight of the wagon and plat orm.

tion, the weighted pulley K keeping the neci essary tension on the hoisting rope H if this operation is continued after the platform is at rest. Any possible slaokening of the rope suiiicient to enable it to free itself from any of the pulleys over which it runs is thereby prevented. `Atl the same time the rotation of the winding drum in this direction raises the counterweights L1.

That I claim is 1. Apparatus for tipping wagonsl comprising ka platform pvoted at one end', a vertically movable hoisting beam-pivoted at its upper end to the opposite end of the platform and extending substantially at right angles thereto at the beginning of the lift, a head on the beam capable of engaging with the rear axle of the wagon, guide rod means hinged to the lower end of the beam, its other end being pivoted on a fixed center, a winding drum and means, passing therefrom over pulleys, to raise and lower the beam and platform, as described. y

2. Apparatus for tipping wagons Comprising a platform pivoted at one end', al vertically movable hoisting beam pivoted at its upper end to the opposite end of the platform and extending substantiall at right angles thereto at the beginning o the lift, a head on the beam capable of engaging with the rear axle ofthe wagon guide rod means hinged to the lower end of the beam, its other end vbeing pivoted on a fixed center, a winding drum and means, passing therefrom over pulleys, to"` raise and lower the beam and platform with means to counterbalance the weight of the platform and wagon, as described'.

3. Apparatus for tippingwagons compris'- ing a platform` pivoted'at` one end, a vertically movablev hoisting beam pivoted at its upper lend to the opposite end of the platform and extending substantially at right angles thereto at the beginning of the lift,'a head on the beam capable of engaging with the rear axle of the wagon, guide rod means hinged to the lower end of the beam, its other end being pivoted on a fixed center, a winding drum and means, passing therefrom over pulleys', to raise and lower 'the beam and platform, extensions on the ends of the winding drum and means passing therefrom to weights counterbalancing the weight of the platform and wagon, as described.

In testimony whereof I have signed my name to this specification.
